Java storing objects in a multidimensional array

I'm attempting to store objects in a multidimensional array in an attempt to save each position in a game boards 'state', however after the loop which is supposed to set each instance to it's own parameters they all end up the same variables. Did I not link the correct array or set it up wrong? There's also a lot of "square.something should be accessed in a static way".

Is square.var or World[x][y].var the correct way for referencing the objects variables?

public static void generateMap() {
    MapSquare[][] World = new MapSquare[10][10]; //2D array init.

    //Choose a square for the home position.
    Random homeRandom = new Random();
    int HomeX = homeRandom.nextInt(10);
    int HomeY = homeRandom.nextInt(10);

    //Chooses a key room.
    int KeyX = homeRandom.nextInt(10);
    int KeyY = homeRandom.nextInt(10);

    //Loop through the objects and set each's parameters.
    for (int i = 0; i < 10; i++)
        {
        for (int j = 0; j < 10; j++)
            {
            MapSquare square = new MapSquare();
            //World[i][j] = square;

            //Calculate the level of the square from the distance to home.
            int distX = HomeX - i;
            int distY = HomeY - j;

            int CalcX = Math.abs(distX); //Convert to positive if negative.
            int CalcY = Math.abs(distY); //Convert to positive if negative.

            //Generate contents of the square.
            int newRandom = random.nextInt(5) + 1;

            switch(newRandom) {
            case 1: // Spawn a monster only.
                {
                square.monster = true;
                square.treasure = false;
                square.trap = false;
                square.home = false;
                square.peekable = false;
                square.key = false;
                square.mapLevel = CalcX + CalcY;

                //Generate the monsters stats.
                Monster monster = new Monster();
                monster.setLevel(square.mapLevel);
                monster.setMaxHealth(monster.getLevel() * 5);
                monster.setHealth(monster.getMaxHealth());
                monster.setDamage(monster.getLevel() * 2);
                break;
                }
            }
            }
        }

    //Generate home square.
    World[HomeX][HomeY].monster = false;
    World[HomeX][HomeY].treasure = false;
    World[HomeX][HomeY].trap = false;
    World[HomeX][HomeY].home = true;
    World[HomeX][HomeY].peekable = true;
    World[HomeX][HomeY].key = false;
    World[HomeX][HomeY].mapLevel = 0;
    World[HomeX][HomeY].visited = true;
    }
